This is stuff they *REALLY* don't teach you in Business School -- but this is the most brutally honest and comprehensive account of "wealth 101" you will probably hear.
In truth, most people probably don't have the constitution for many of the stomach-turning tactics described herein -- but this book tells no lies. This book may violate your sense of "fairness" -- which is precisely why these men are (were) wealthy and you are not.
Covering tactics of wealth builders over the last 100 years this book is morbidly fascinating in the way that watching a spider dissect a fly is fascinating. I recommend it.
Historical information interesting but no practical advice for the normal person.
